Chemicals in Water

Passive sampling of perfluorinated chemicals in water: in-situ calibration.

Perfluorinated chemicals (PFCs) have been recognised as environmental pollutants that require monitoring. A modified polar organic chemical integrative sampler (POCIS) is able to quantify aqueous PFCs. However, with varying external water velocity, PFC sampling rates (Rs) may change, affecting accuracy of derived water concentrations. To facilitate field deployment of this sampler, two methods ...

Which chemicals drive biological effects in wastewater and recycled water?

Removal of organic micropollutants from wastewater during secondary treatment followed by reverse osmosis and UV disinfection was evaluated by a combination of four in-vitro cell-based bioassays and chemical analysis of 299 organic compounds. Concentrations detected in recycled water were below the Australian Guidelines for Water Recycling. Thus the detected chemicals were considered not to pos...

PUBLIC HEALTH GOALS FOR CHEMICALS IN DRINKING WATER Water Soluble Polychlorinated Biphenyls Expected to be Found in Drinking Water

with whom the Office of Environmental Health Hazard Assessment contracted through the University of California Office of the President for their peer reviews of the public health goal documents, and gratefully acknowledge the comments received from all interested parties. This Public Health Goal (PHG) technical support document provides information on health effects from contaminants in drinkin...

Analysis of liquids and chemicals costs in a sample port

In recent years, the application of Activity-Based Costing in Port industry has been deeply researched in theory and practice, but researchers only concentrate on the bulk and general cargo’s ABC in loading and unloading operations and there is little about the liquids and chemicals’. Based on the liquids and chemicals’ handling process and the particularity of their cost accounting, the paper ...
