Determination of Lead Content in Pyrotechnics Used for Fireworks And
Advances in Engineering Research (AER), volume 130 5th International Conference on Frontiers of Manufacturing Science and Measuring Technology (FMSMT 2017) Determination of lead content in pyrotechnics used for fireworks and firecrackers based on inductively coupled plasma optical emission spectrometric approach (ICP-OES) 1, a Wu Jun-yi 1Technical Center for Dangerous Goods Testing of Guangxi Entry-Exit Inspection and Quarantine Bureau, Beihai, Guangxi, China [email protected] Keywords: fireworks and firecrackers; pyrotechnics; lead content; determination; inductively coupled plasma optical emission spectrometric approach; ICP-OES. Abstract. Inductively coupled plasma optical emission spectrometric approach(ICP-OES) is used to determine the lead content in pyrotechnics used for fireworks and firecrackers. Element of lead is commonly found as impurity in chemical materials used for pyrotechnics in fireworks and firecrackers. Statistical analysis shows that lead content in pyrotechnics is below 5%.Concept of this method: considering the weight of the sample is 400mg,constant volume is 0.5L and the concentration of lead is below 40mg/L in sample solution, the determination scope of the method for the lead content would be between 5%.Further experiments proved that the fitting correlation coefficient of lead calibration curve is 0.9997 or higher, recovery is 92.53%‒115.63%.The allowable differential value is 0.4% between two single tests under repeatable conditions. This method can completely satisfy the requirements of the fireworks and firecrackers industry with high accuracy and good precision. Introduction In China, fireworks and firecrackers are very important consumer recreational products in people’s everyday life since ancient times. Gorgeous colors produced by fireworks and firecrackers are even the leading role of foiling festal atmosphere in every grand holiday celebrations. -

Palm Tree Care
Palm Tree Care Introduction To think of Florida without imagining palm lined beaches, pink flamingos, and blue water is difficult. Palms trees are synonymous with our semi-tropical climate. This brochure will help you learn the basic needs of these tropical treasures. Palm Selection: Look at neighborhood palms and see which ones seem to thrive in your area. Take advantage of the many local nurseries within Broward County where you can see the many varieties of palms available. In most cases you can select and tag the palm that will be delivered to your property. Finally, you might go to one of your County Library Branches and look at a Florida Landscape Plants reference guide. You can obtain many ideas for Species selection and placement that could save you much time and effort. Lethal Yellowing susceptibility of many of Florida's palms makes it prudent to select a resistant species. This disease causes the bloom to turn black and the immature fruit to drop, followed by the yellowing of fronds from the lower to the upper areas, culminating in bud rot and subsequent death. Lethal Yellowing is transferred by the insect planthopper or leafhopper (Myndus crudus). Manila palms and many varieties of the Coconut palm are particularly vulnerable to this disease. Native palms are generally more resistant. These include Sabal palm, Royal palm, Paurotis palm, Florida Thatch palm and Key Thatch palms. Non- native resistant palms include Alexander, Queen, Washingtonia, Maypan Coconut, and other species. Further information about resistant palms can be obtained from the Broward County Cooperative Extension Service. -
The Miracle Resource Eco-Link
Since 1989 Eco-Link Linking Social, Economic, and Ecological Issues The Miracle Resource Volume 14, Number 1 In the children’s book “The Giving Tree” by Shel Silverstein the main character is shown to beneÞ t in several ways from the generosity of one tree. The tree is a source of recreation, commodities, and solace. In this parable of giving, one is impressed by the wealth that a simple tree has to offer people: shade, food, lumber, comfort. And if we look beyond the wealth of a single tree to the benefits that we derive from entire forests one cannot help but be impressed by the bounty unmatched by any other natural resource in the world. That’s why trees are called the miracle resource. The forest is a factory where trees manufacture wood using energy from the sun, water and nutrients from the soil, and carbon dioxide from the atmosphere. In healthy growing forests, trees produce pure oxygen for us to breathe. Forests also provide clean air and water, wildlife habitat, and recreation opportunities to renew our spirits. Forests, trees, and wood have always been essential to civilization. In ancient Mesopotamia (now Iraq), the value of wood was equal to that of precious gems, stones, and metals. In Mycenaean Greece, wood was used to feed the great bronze furnaces that forged Greek culture. Rome’s monetary system was based on silver which required huge quantities of wood to convert ore into metal. For thousands of years, wood has been used for weapons and ships of war. Nations rose and fell based on their use and misuse of the forest resource. -

Burning in Naval Stores Forest
Proceedings: 3rd Tall Timbers Fire Ecology Conference 1964 Burning in Naval Stores Forest NORMAN R. HAWLEY Naval Stores Conservation Program U. S. Forest Service Valdosta, Georgia BEFORE discussing woods burning in naval stores, what is naval stores? First, be it understood that there are three fields within the activity, namely (1) wood distillation, or the process of obtaining the desired product from pine stumps; (2) the capture of tall oil in the sulfate pulping process, and (3) gum naval stores, or the harvesting of oleoresin or gum from standing, living pine trees, ob tained throughout a long working season of some seven months annually. Today, I shall discuss fire in its relation to the gum naval stores business. But first, how did the activity derive its odd name? There is cause for puzzlement. The story is told-with tongue in cheek-that a Secretary of the Navy, somewhat confused, but firm in his resolve to be prepared, declared: "I don't know what it is, but let's get some of it!" The term is a carry-over from the days of sail. Then the product was in prime demand. It caulked the hulls of wooden ships, and treated rigging against the erosive action of sun, rain, wind, ice, and salt water. How old is the business? We know that flammable gum featured heavily in the combustibles tossed around in ancient Mediterranean sea fights. Some writers speak with authority that it dates from the year 315 B. C. Others point to the Bible and quote from chapter and verse how Noah treated the hull of the Ark with derivatives from the 81 NORMAN R. -

Medina , Jose Hermis P. Patricio, and Angela Grace Toledo-Bruno Department of Environmental Science, College of Forestry and Environmental Science Central Mindanao University, University Town, Musuan, Bukidnon, Philippines Abstract. Aside from the greenhouse gas reduction ability of palm oil-based biofuel as alternative to fossil fuels, another essential greenhouse gas mitigation ability of oil palm plantation is in terms of offsetting anthropogenic carbon emissions through carbon sequestration. In this context, this study was done to determine the carbon sequestration potential of oil palm plantations specifically in two areas in Mindanao, Philippines. Allometric equation was used in calculating the biomass of oil palm trunk. Furthermore, destructive methods were used to determine the biomass in other oil palm parts (fronds, leaves, and fruits). Carbon stocks from the other carbon pools in the oil palm plantations were measured which includes understory, litterfall, and soil. Results revealed that the average carbon stock in the oil palm plantations is 40.33 tC/ha. Majority of the carbon stock is found in the oil palm plant (53%), followed by soil (38%), litterfall (6%), and understory, (4%). The average carbon sequestration rate of oil palm plants is estimated to be 4.55 tC/ha/year. -

Wildland fire in ecosystems: fire and nonnative invasive plants. Gen. Tech. Rep. RMRS-GTR-42-vol. 6. Ogden, UT: U.S. Department of Agriculture, Forest Service, Rocky Mountain Research Station. 355 p. Abstract—This state-of-knowledge review of information on relationships between wildland fire and nonnative invasive plants can assist fire managers and other land managers concerned with prevention, detection, and eradi- cation or control of nonnative invasive plants. The 16 chapters in this volume synthesize ecological and botanical principles regarding relationships between wildland fire and nonnative invasive plants, identify the nonnative invasive species currently of greatest concern in major bioregions of the United States, and describe emerging fire-invasive issues in each bioregion and throughout the nation. This volume can help increase understanding of plant invasions and fire and can be used in fire management and ecosystem-based management planning. The volume’s first part summarizes fundamental concepts regarding fire effects on invasions by nonnative plants, effects of plant invasions on fuels and fire regimes, and use of fire to control plant invasions. The second part identifies the nonnative invasive species of greatest concern and synthesizes information on the three topics covered in part one for nonnative inva- sives in seven major bioregions of the United States: Northeast, Southeast, Central, Interior West, Southwest Coastal, Northwest Coastal (including Alaska), and Hawaiian Islands. -

All comments must be received by December 15, 1996, for consideration for the First Supplement. ____________________________________________________________________________________ May 31, 1996 Spice Oleoresins DESCRIPTION Spice Oleoresins used in foods are derived from spices and contain the total sapid, odorous, and related characterizing principles normally associated with the respective spices. The oleoresins are produced by one of the following processes: (1) by extraction of the spice with any suitable solvent or solvents, in combination or sequence, followed by removal of the solvent or solvents in conformance with applicable residual solvent regulations (see General Requirements below), or (2) by removal of the volatile portion of the spice by distillation, followed by extraction of the nonvolatile portion, which after solvent removal is combined with the total volatile portion. Spice Oleoresins are frequently used in commerce with added suitable food-grade diluents, preservatives, antioxidants, and other substances consistent with good manufacturing practice, as provided for under Added Substances (see General Provisions). When added substances are used, they must be declared on the label in accordance with current U.S. regulations or with the regulations of other countries that recognize the Food Chemicals Codex. The Spice Oleoresins covered by this monograph are Oleoresin Angelica Seed Obtained by the solvent extraction of the dried seed of Angelica archangelica Linnaeus as a dark brown or green liquid. -

Four hundred years later, a scant 3 percent of what was known as “the great piney woods” remains. The trees’ abundance grew the Southeast’s first major industry, one that served the world’s biggest fleet, the British Navy, with the naval stores essential to shipbuilding and maintenance. The pines yielded gum resin, rosin, pitch, tar, and turpentine.
