Perchlorate in shellfish from South China Sea and implications for human exposure

Trends in the Exposure, Distribution, and Health Risk Assessment of Perchlorate among Crayfish in the Middle and Lower Reaches of the Yangtze River

“…Previous studies have investigated perchlorate exposure levels in shellfish. For shellfish distributed in the south China sea, they were detected with a median perchlorate level of 4.33 μg/kg, which is lower than that found in our present study [ 15 ]. A study on perchlorate exposure levels in various foods from Chengdu showed that the median perchlorate contaminate level in scallops is 5.63 μg/kg, which is also lower than our results here [ 11 ].…”

“…Therefore, it is also critical to study human exposure to perchlorate in aquatic food. A previous study of perchlorate exposure in shellfish indicated that perchlorate ubiquitously occurred in shellfish from the South China Sea, with a consequential high detection frequency (99.4%) [ 15 ]. In addition, perchlorate has been found in other fish as well [ 3 , 11 ].…”

Occurrence, spatial distribution, and risk assessment of perchlorate in tea from typical regions in China

“…Plants can absorb and enrich perchlorate from water and soil, and finally enter the human body through the food chain ( Kumarathilaka et al, 2016 ). At present, perchlorate was detected in vegetables, fruits, dairy products, aquatic products, meats, and other food categories ( Abt et al, 2018 ; Chen et al, 2021 ; Chen et al, 2022 ; Chen et al, 2023 ; EFSA, 2017 ; Kim et al, 2014 ; Lee et al, 2012 ; Li et al, 2022 ; Liao et al, 2020 ; Wang et al, 2021 ), which has aroused widespread concerns. Other exposure pathways of perchlorate also include ingestion and inhalation of indoor dust, as well as atmospheric dust ( Jiang et al, 2021 ; Wan et al, 2015 ).…”
