Appendix a Analysis of Products with Two Or More Active Ingredients
APPENDIX A ANALYSIS OF PRODUCTS WITH TWO OR MORE ACTIVE INGREDIENTS The Agency does not routinely include, in its risk assessments, an evaluation of mixtures of active ingredients, either those mixtures of multiple active ingredients in product formulations or those in the applicator’s tank. In the case of the product formulations of active ingredients (that is, a registered product containing more than one active ingredient), each active ingredient is subject to an individual risk assessment for regulatory decision regarding the active ingredient on a particular use site. If effects data are available for a formulated product containing more than one active ingredient, they may be used qualitatively or quantitatively1 2. There are no product LD50 values, with associated 95% Confidence Intervals (CIs) available for glyphosate. As discussed in USEPA (2000) a quantitative component-based evaluation of mixture toxicity requires data of appropriate quality for each component of a mixture. In this mixture evaluation an LD50 with associated 95% CI is needed for the formulated product. The same quality of data is also required for each component of the mixture. Given that the formulated products for glyphosate do not have LD50 data available it is not possible to undertake a quantitative or qualitative analysis for potential interactive effects. However, because the active ingredients are not expected to have similar mechanisms of action, metabolites, or toxicokinetic behavior, it is reasonable to conclude that an assumption of dose-addition would be inappropriate. Consequently, an assessment based on the toxicity of glyphosate is the only reasonable approach that employs the available data to address the potential acute risks of the formulated products. -

In this research the microbial biodegradation of aclonifen was investigated using liquid and soil experiments with identified cultures and mixed consortia. Isolated fungi and bacteria consortia showed the highest degradation at 93% of the Chemical Oxygen Demand (COD) parameter over five days. Bacteria mix and fungi mix performed 90% and 91% degradation in five days, as COD, while 71% and 91% were active ingredients. For Total Organic Carbon (TOC) experimental results, bacteria mix, fungi mix, and bacteria and fungi mix, showed 86%, 88% and 88% respectively. Soil studies with mixed cultures of bacteria and fungi performed the most efficient degradation, at 97% after five weeks. The degradation of aclonifen by 2 ml mixed cultures showed about 63% of degradation in five weeks and 5 ml of mixed cultures showed about 90% in six weeks. Keywords: microbial biodegradation, aclonifen, mixed consortia, chemical oxygen demand, total organic carbon Introduction One of the main factors of environmental pollution is the excessive use of chemicals and pesticides, used on a global scale, to increase production and for the protection of crops. -

OCCUPATIONAL EXPOSURE DURING THE MANUFACTURE AND FORMULATION OF PESTICIDES * U.S. DEPARTMENT OF HEALTH, EDUCATION, AND WELFARE Public Health Service Center for Disease Control National Institute for Occupational Safety and Health July 1978 For sale by the Superintendent of Documents, U.S. Government Printing Office, Washington, D.C. 20402 DISCLAIMER Mention of company names or products does not constitute endorsement by the National Institute for Occupational Safety and Health. DHEW (NIOSH) Publication No. 78-174 PREFACE The Occupational Safety and Health Act of 1970 emphasizes the need for standards to protect the health and provide for the safety of workers occupationally exposed to an ever-increasing number of potential hazards. The National Institute for Occupational Safety and Health (NIOSH) has implemented a formal system of research, with priorities determined on the basis of specified indices, to provide relevant data from which valid criteria for effective standards can be derived. Recommended standards for occupational exposure, which are the result of this work, are based on the effects of exposure on health. The Secretary of Labor will weigh these recommendations along with other considerations, such as feasibility and means of implementation, in developing regulatory standards. Successive reports will be presented as research and epideiriologic studies are completed and as sampling and analytical methods are developed. Criteria and standards will be reviewed periodically to ensure continuing protection of workers. The contributions to this document on pesticide manufacturing and formulating industries by NIOSH staff members, the review consultants, the reviewer selected by the American Conference of Governmental Industrial Hygienists (ACGIH), other Federal agencies, and by Robert B. -

The overall objectives of the IPCS are to establish the scientific basis for assessment of the risk to human health and the environment from exposure to chemicals, through international peer review processes, as a prerequisite for the promotion of chemical safety, and to provide technical assistance in strengthening national capacities for the sound management of chemicals. This publication was developed in the IOMC context. The contents do not necessarily reflect the views or stated policies of individual IOMC Participating Organizations. The Inter-Organization Programme for the Sound Management of Chemicals (IOMC) was established in 1995 following recommendations made by the 1992 UN Conference on Environment and Development to strengthen cooperation and increase international coordination in the field of chemical safety. The Participating Organizations are: FAO, ILO, UNDP, UNEP, UNIDO, UNITAR, WHO, World Bank and OECD. The purpose of the IOMC is to promote coordination of the policies and activities pursued by the Participating Organizations, jointly or separately, to achieve the sound management of chemicals in relation to human health and the environment.
