Occurrence of perchlorate in processed foods manufactured in China

, 2020
Perchlorate has been recognized as a new threat to the environment and foods, which may cause serious health problems. The information on perchlorate contamination in water and food samples in China is limited.

Dietary exposure assessment to perchlorate in the Taiwanese population: A risk assessment based on the probabilistic approach.

Environmental Pollution, 2020
Perchlorate is an endocrine-disrupting chemical (EDC) that contaminate various foodstuffs. Exposure to perchlorate may cause severe health problems, mainly thyroid dysfunction. However, information on perchlorate contamination of consumer foods in Taiwan

A facile low-temperature synthesis of hierarchical porous Co3O4 micro/nano structures derived from ZIF-67 assisted by ammonium perchlorate

Inorganic Chemistry Frontiers, 2019
Sub-micro hierarchical porous Co3O4 dodecahedra with a large specific surface area (106.11 m2 g−1) were synthesized by the thermolysis of ZIF-67 at a low temperature of 268 °C assisted by ammonium perchlorate (AP).

How nitrate affects perchlorate reduction in a methane-based biofilm batch reactor.

Water Research, 2019
Nitrate (NO3-) affected perchlorate (ClO4-) reduction in a membrane batch biofilm reactor (MBBR), even though the electron donor, CH4, was available well in excess of its demand.

Microidentification of cupric and perchlorate ions as cupric pyridine perchlorate

Mikrochemie Vereinigt mit Mikrochimica Acta, 1947
A microchemical test involving the formation of Cu(C5H5N)4(ClO4)2 in perfect crystals, the edge or profile angles of which can be accurately measured, is proposed for the cupric and perchlorate ions. Some properties, including the values of the angles mentioned, are described, and an analysis of cupric pyridine perchlorate is presented.

Perchlorate bio-reduction in a methane-based membrane biofilm reactor in the presence and absence of oxygen.

Water Research, 2019
Perchlorate has been widely detected in various water environments and could cause serious health problems. Methane has been proposed as a promising electron donor to remove perchlorate from contaminated water, yet it is unclear whether and how microbial

Environmental exposure to perchlorate: A review of toxicology and human health

Toxicology and Applied Pharmacology, 2018
Perchlorate pharmacology and toxicology studies date back at least 65 years in the peer‐reviewed literature. Repeated studies in animals and humans have demonstrated perchlorate's mechanism of action, dose‐response, and adverse effects over a range of ...

Ammonium perchlorate and ammonium perchlorate-binder sandwich combustion

12th Aerospace Sciences Meeting, 1974
order of 300 \i in width. The deflagration of all three burners appeared laminar, with a definite temperature peak above the center of the burner. The PP-COMM AP had a scalloped surface which accounted for a more unsteady appearance of the gas flow above the deflagrating AP. A yellow-green zone was visible within the SC-UHP AP extending from the burner

Quantitative determination and contamination pattern of perchlorate in tea by ultra performance liquid chromatography and tandem mass spectrometry.

Food Chemistry, 2019
Perchlorate causes great health concerns for its inhibition on the iodide intake of human. However, the contamination pattern of perchlorate in tea remains unclear although tea is substantially consumed worldwide.

Evidence for Biotic Perchlorate Reduction in Naturally Perchlorate-Rich Sediments of Pilot Valley Basin, Utah

Astrobiology, 2019
The presence of perchlorate on Mars suggests a possible energy source for sustaining microbial life. Perchlorate-reducing microbes have been isolated from perchlorate-contaminated soils and sediments on the Earth, but to date, never from an environment ...
