Seasonal changes in organotin compounds in sediments from the Bahía Blanca Estuary

Organotin compounds in Brachidontes rodriguezii mussels from the Bahía Blanca Estuary, Argentina

“…The procedure used is similar to that previously applied to sediment samples described in Quintas et al (2016) using 10 mL of 0.1% sodium hydroxide in methanol instead of the original volume.…”

Organotin Release from Polyvinyl Chloride Microplastics and Concurrent Photodegradation in Water: Impacts from Salinity, Dissolved Organic Matter, and Light Exposure

“…Organotin compounds (OTCs) are one of the man-made organometallic derivatives with endocrine disrupting effects. , Besides as biocides and fungicides, OTCs have been used as light and thermal stabilizers in PVC plastics for more than 40 years, accounting for 3.5% of the total tin consumption worldwide . Meanwhile, PVC polymers have broad applications in pipes, hoses, toys, medical devices, and automotive parts and account for about 73% of the annual global production of plasticizers (e.g., phthalate, benzophenones, and also OTCs). − Thus, waste PVC or its debris may enter the environment and contribute to the release of embedded chemicals.…”

The use of ultrasound in the South Cone region. Advances in organic and inorganic synthesis and in analytical methods

“…Then, 2 mL of hexane, 100 mg of sodium borohydride, sonicated (USB) for 1 min, 1 h at 0 °C. Enhanced the enrichment factor [103] Faecal contaminants (sterols) Sediments UAE ES: Dichloromethane 5 g of lyophilized sample, 10 mL of dichloromethane and 5 mL of methanol immersed for 30 min (three times) in an USB (Eco-Sonics (Q3.0/40), 40 kHz). The extracts were combined and concentrated to approximately 2 mL by rotoevaporation.…”

“…Organotin compounds were determined in sediments from the Bahía Blanca Estuary by Quintas et al . (Argentina) [103] . By means of a novel extraction procedure assisted by ultrasound, it was possible the detection of organotin compounds in all the sediments tested.…”
