It will address the poor synthesis of available information, develop a basic strategy to cope with the problem and deal with chemical, toxicological, medical, epidemiological, nutritional and public health issues, as well as removal technology and water quality management. An update of WHO's International Programme on Chemical Safety Environmental Health Criteria Monograph on Arsenic, addressing all aspects of risks to human health and the environment, is also under preparation. Even where AAS is available, quality control and external validation may remain a problem. New types of treatment technologies, including co-precipitation treatment, ion exchange, activated alumina filtration, and chemical packages for household treatment, are being tested. Some studies have reported preliminary successes in using packets of chemicals for household treatment.
Some mixtures combine arsenic removal with disinfection.
Increased availability and dissemination of all information. Robust technologies for arsenic removal at wells and in households. In these studies, wells were not randomly selected and the proportion does not reflect the real proportion of wells contaminated. The poor availability of reliable information hinders action at all levels and may lead to panic, exacerbated if misleading reports are made. Effective information channels have yet to be established to those affected and concerned.
