To better understand the composition of contaminants of emerging concern (CECs) in landfill leachate, fresh leachate from 19 landfills was sampled across the United States during 2011. The sampled network included 12 municipal and 7 private landfills with varying landfill waste compositions, geographic and climatic settings, ages of waste, waste loads, and leachate production. A total of 129 ou...

Phthalates are widely used as plasticizers to make polymers more flexible in industrial and household products. However, lower molecular weight ortho-phthalate plasticizers have serious health effects and are restricted or banned in many countries for use in children’s products. In addition, several government agencies restrict or are investigating restricting ortho-phthalates (ortho-dialkyl ph...

Silica sand is widely used in the transformation industry. For instance, it is used in the making of glass, silicates, paints, glass-ceramics and ceramics. Traditionally, glass and ceramic materials have been manufactured using high-purity silica and minerals taken from ore on the surface of the earth. However, during recent decades, the manufacture of household and industrial products has incr...

This study combines longitudinal individual-level data with neighborhood-level industrial hazard data to examine the extent and sources of environmental inequality. Results indicate that profound racial and ethnic differences in proximity to industrial pollution persist when differences in individual education, household income, and other microlevel characteristics are controlled. Examination o...

This strongly alkaline chemical is widely used in industry as a feed stock for nitrogen-based chemicals such as fertilizers, plastics and explosives (ATSDR, 1990). Ammonia is also used as a refrigerant. The general public is exposed by off-gasing from cleaning solutions containing aqueous ammonia. Household ammonia solutions contain 5-10% ammonia in water while industrial strength can be up to ...

Thailand has been changed to rapid urbanization and industrialization since 1980s. During 1992 through 1996, the number of industrial factories in Rayong province increased very sharply. The major types of industries are petrol-chemical and plastic production. However, after the petrochemical industry boomed, the higher demand led to an industrial area expansion. The establishment of factories ...

The calorific value of household refuse (HR) is greatly improved after classification, which includes the implementation sufficient pyrolysis conditions. Therefore, a better effect can be achieved by co-pyrolysis with industrial solid waste (ISW) high value. In this work, HR and ISW were used as raw materials for experiments. influence on distribution three-phase products co-pyrolysis, concentr...
