EPA LEAF Methods for Leaching Assessment
This article discusses the differences and benefits of using EPA LEAF methods as an alternative to TCLP for solid materials. Employed in the laboratory, LEAF methods provide improved control of key factors that can affect leaching in on-site TCLP testing.
Neonicotinoids Pesticides and Metabolites
Neonicotinoids have established themselves as key components in insecticides because of their unique selectivity. The mode of action is similar to nicotine.
Analytical Method: Urea in Water and Wastewater, Enzymatic Determination
Urea in water and wastewater, enzymatic determination - Photometric determination using the indophenol blue method after cleavage of the urea
Safe Drinking Water Act & Clean Water Act – What is it?
The Safe Drinking Water Act reflects the primary drinking water regulation. Drinking water here means finished drinking water from the plant and the distribution lines. But the Safe Drinking Water Act covers also the ground water sources for raw water
Membrane Filters for Microplastics Analysis
An overview of microplastics, testing regulations, and filter selection for microplastic sample collection, preparation, and analysis.
Drinking Water Testing by Ion Chromatography using Ultrapure Water
This study reviews the suitability of ultrapure water for the IC analysis of drinking water. Inorganic ions and disinfectant by-products (DBPs) were assessed.
