It offers information on glyphosate and the many ramifications of an International Agency for Cancer Research (IARC) classification. It mentions status of glyphosate determined by the U.S. Environmental Protection Agency (EPA) and the European Chemicals Agency (ECHA). It states categories of IARC which involves carcinogenic agents and carcinogenicity.

The United States has restated its opposition to an EU proposal to classify titanium dioxide and cobalt as possible carcinogens, asking the European Commission (EC) to consult with the World Trade Organization (WTO) before taking further action. [ABSTRACT FROM AUTHOR]

The United States has challenged European Union proposals to label titanium dioxide and cobalt as carcinogens on free-trade grounds. [ABSTRACT FROM AUTHOR]

Reports on research from Spain which revealed the use of a novel method to assess DNA damage after exposure to benzo(a)pyrene. Association of genotoxins in the aquatic environment with the decline of many wild populations; Hazard assessment of chemicals; Establishment of the maximum allowable chemical concentrations prior to the release to the environment.

Ralph Nader warned the feds in the early 1970s [ABSTRACT FROM PUBLISHER]

Presents the development of a method that evaluated the exposure and health risk to children from swimming in outdoor pools filled with contaminated water. Increase in the dermal absorption of trichloroethylene (TCE); Percentage rate of dermal absorption of TCE; Range of estimated exposures of TCE per swimming.

A number of fungal cultures were screened to select an organism suitable to be used in the detoxification of aflatoxin B1. They were co-cultured in Czapek-Dox-Casamino acid medium with aflatoxin B1 producing Aspergillus flavus. Several fungal cultures were found to prevent synthesis of aflatoxin B1 in liquid culture medium. Among these Phoma sp., Mucor sp., Trichoderma harzianum, Trichoderma sp. 639, Rhizopus sp. 663, Rhizopus sp. 710, Rhizopus sp. 668, Alternaria sp. and some strains belonging to the Sporotrichum group (ADA IV B14(a), ADA SF VIBF (9), strain 720) could inhibit aflatoxin synthesis by =/>90 %. A few fungi, namely ADA IV B1, ADA F1, ADA F8, also belonging to the Sporotrichum group, were less efficient than the Phoma sp. The Cladosporium sp. and A. terreus sp. were by far the least efficient, registering <10 % inhibition. The cultures which prevent aflatoxin biosynthesis are also capable of degrading the preformed toxin. Among these, Phoma sp. was the most efficient destroying about 99 % of aflatoxin B1.The cell free extract of Phoma sp. destroyed nearly 50 5g aflatoxin B1 100 ml-1 culture medium (90 % of the added toxin), and this was more effective than its own culture filtrate over 5 days incubation at 28 +/-2 deg. C. The degradation was gradual: 35 % at 24 h, 58 % at 48 h, 65 % at 72 h, 85 % at 96 h and 90 % at 120 h. The possibility of a heat stable enzymatic activity in the cell free extractof Phoma is proposed. [ABSTRACT FROM AUTHOR]

In 1996, the Food Quality Protection Act (FQPA) made major changes in the law governing pesticide residues in food, including eliminationof the zero-risk standard for carcinogenic food additives. The FQPA instead imposed a new safety standard -- a reasonable certainty that no ham will result from aggregate exposure to the pesticide -- for establishment of 'tolerances' setting maximum allowable amounts of pesticide residue. In this Article, the authors assess the significant regulatory challenges this new standard poses. They examine the factorsEPA must consider in establishing tolerances, including information on the aggregate exposure to a given pesticide and the cumulative effects of pesticides with a common mechanism of toxicity. The authors trace EPA's efforts to begin implementation of the new law and explorethe practical and scientific difficulties of developing reliable information on which to base tolerance decisions. They conclude that establishment of tolerances under the FQPA will be challenging, but workable, if EPA relies on and provides sufficient time for collection ofgood data. [ABSTRACT FROM AUTHOR]
