Influence of chemicals commonly found in a water environment on the Salmonella mutagenicity test

The Science of the Total Environment

Abstract

The influence of 16 organic chemicals commonly found in a water environment--such as phenols, phthalic esters and phosphoric esters--on the Salmonella mutagenicity test was investigated. The test chemicals were subjected to the mutagenicity test using a fixed dose of various positive standard mutagens such as 2-nitrofluorene, Trp-P-1, Trp-P-2, 2-aminofluorene and benzo[a]pyrene, thus testing them for their influence on the mutagenic activities. The influence of each chemical was classified into one of five groups as follows: (1) toxic and inhibitory to mutagenicity; (2) toxic and promotive to mutagenicity; (3) non-toxic and inhibitory to mutagenicity; (4) non-toxic and promotive to mutagenicity; and (5) non-toxic and having no effect on mutagenicity. It is concluded that chemicals in the water environment may influence the results of a mutagenicity test on environmental samples. In particular, an effect may be noted with regard to wastewater and sediments which contain these chemicals in higher concentrations eventhough they themselves are not mutagenic.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
