Following the attack of September 11th, public opinion polls showed a remarkable leap in Americans’ trust of their government. Some in New York City seem to be carving out an exception to that trust when it comes to the US Environmental Protection Agency. Fanned by some alarming news reports, there are doubts about whether the EPA has been telling the truth about the New York City air. In the w...
EPA Method 1615 measures enteroviruses and noroviruses present in environmental and drinking waters. This method was developed with the goal of having a standardized method for use in multiple analytical laboratories during monitoring period 3 of the Unregulated Contaminant Monitoring Rule. Herein we present the protocol for extraction of viral ribonucleic acid (RNA) from water sample concentra...
for pulp and paper manufacture. The science, a proven environmental track record, and strong market demand demonstrate that ECF is without rival in terms of pollution prevention, resource conservation, and product quality. "Chlorine dioxide is a solution to dioxin and other persistent, bio-accumulative, toxic substances in mill waste water." [1] Dr. Robert Huggett, former U.S. EPA Assistant Adm...
In August 2002, the U.S. Environmental Protection Agency (EPA) proposed national regulations to control pollutant discharges from the wastewaters of the aquatic animal production (AAP) industry. In developing this proposed rule, EPA collected information from the AAP industry by using a two-phase sample design. In the first phase, EPA conducted a census of the industry using a screener question...
The whitefly (Bemisia tabaci Gennadius) is a notorious devastating sap-sucking insect pest that causes substantial crop damage and yield losses due to direct feeding by both nymphs adults also through transmission of viruses diseases. Although the foliar application synthetic pesticides crucial for efficient control B. tabaci, it has adverse effects such as environmental pollution, resistance r...
Second-hand smoking (passive smoking or environmental smoke exposure) refers to air inhaled by a nonsmoker that is contaminated by smoke released from a burning cigarette or in the exhaled air of a person smoking a cigarette. More than 4,000 chemicals, including at least 43 known cancer-causing agents, have been identified from environmental smoke.1 In 1993, the United States Environmental Prot...
Recent advances in molecular and cellular biology allow for measurement of biologic events or substances that may provide markers of exposure, effect, or susceptibility in humans. The application of these new and emerging techniques to environmental health offers the possibility of significantly reducing the uncertainties that traditionally hamper risk assessments. The U.S. Environmental Protec...
F or longevity, few issues in the forest products industry rival the formaldehyde (HCHO) debate. The issue came to the fore in the mid-1970s as increased use of HCHO-emitting board products in more tightly constructed homes led to numerous complaints. As a result. U.S. Housing and Urban Development Agency (HUD) ruled in 1985 that the HCHO level of air in mobile homes would be limited to 0.4 par...
Nutritional enhancement of crops using genetic engineering can potentially affect herbivorous pests. Recently, oilseed crops have been genetically engineered to produce the long-chain omega-3 polyunsaturated fatty acids, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) at levels similar to that found in fish oil; to provide a more sustainable source of these compounds than is currentl...
