Cumulative influences of a small city and former mining activities on the sediment quality of a subtropical estuarine protected area
(Springer, 2014-11-01)
This study aimed to evaluate the sediment quality in the estuarine protected area known as Canan,ia-Iguape-Peruibe (CIP-PA), located on the southeastern coast of Brazil. The study was designed considering possible negative ...
Delayed and time-cumulative toxicity of imidacloprid in bees, ants and termites
(2014)
Imidacloprid, one of the most commonly used insecticides, is highly toxic to bees and other beneficial insects. The regulatory challenge to determine safe levels of residual pesticides can benefit from information about ...

Bioaccumulation and acute toxicity of As(III) and As(V) in Nile tilapia (Oreochromis niloticus)
(2019-02-01)
The distribution of arsenic in the different tissues of tilapia fish is determined by the exposure time and the depuration rate. The mechanisms of toxicity/carcinogenicity depend on the arsenic species involved in the ...
Environmentally relevant mixtures in cumulative assessments: An acute study of toxicokinetics and effects on motor activity in rats exposed to a mixture of pyrethroids
(Oxford University Press, 2012-12)
Due to extensive use, human exposure to multiple pyrethroid insecticides occurs frequently. Studies of pyrethroid neurotoxicity suggest a common mode of toxicity and that pyrethroids should be considered cumulatively to ...
Relationship between exposure, body burden and target tissue concentration after oral administration of a low-dose mixture of pyrethroid insecticides in young adult rats
(Elsevier Ireland, 2018-11)
Pyrethroids (PYRs) are synthetic insecticides increasingly used in agricultural and household pest control. Little is known on how the toxicity of highly effective bolus doses of single compounds compares to more realistic ...
Effectiveness and Safety of Reirradiation With Stereotactic Ablative Radiotherapy of Lung Cancer After a First Course of Thoracic Radiation: A Meta-analysis
(2020-08-01)
OBJECTIVE: The effectiveness and safety of reirradiation with stereotactic ablative radiotherapy (re-SABR) in patients with recurrence after a previous course of radiation are limited to small series. We carried out a ...
