Biosolids are the solid by-product of wastewater treatment system. They regularly applied to agricultural land in UK fertilize and increase crop yields, but they have been shown contain high concentrations microplastics. Here we sampled a selection soils Southeast England which had received or never biosolid treatment. Sites were on two occasions summer winter. Microplastic (MP) numbers both treated fields (874 MP/kg) untreated (664 wide variety polymers found across sites. However, there...

A microwave digestion procedure was developed for multi-element determinations in tree foliage by inductively coupled plasma–atomic emission spectrometry. The involved the sequential of 0.500 g plant material with HNO 3 (10 mL), H 2 O (1 and HCl (2 mL) at 90% power 30 min, 15 30% 10 respectively. proposed method gave Ca, Mg, K, Na, Mn, P, S results good agreement National Institute Standards Technology reference materials. Iron aluminum concentrations were 20 to lower than certified values....

Seagrass meadows are one of the world's most diverse ecosystems offering habitats for an extensive array species, as well serving protectors coral reefs and vital carbon sinks. Furthermore, they modify hydrodynamics by diminishing water flow velocities enhancing sediment deposition, indicating potential microplastic accumulation in their sediments. The build-up microplastics could potentially have ecological impacts threatening to ecosystems, however little is known about abundance...

Abstract Little information exists on the accuracy, precision, and make‐up of extractable S in surface organic horizons forest soils. Eight extractants (H 2 O, 0.01 M CaCl , KCl, LiCl, 0.003 NH 4 OAc, Cl, 500 mg P L −1 as Ca(H PO ) ·H O) were evaluated for extraction determination SO ‐S total five The analyses performed by ion chromatography (IC) inductively coupled plasma atomic emission spectrometry (ICP‐AES), respectively. Each weak salt removed similar amounts S. Water was least...

Abstract Many of the methods for microplastics quantification in environment are criticised creating problems with data validity. Quantification surface microlayer aquatic environments using glass plate dipping holds promise as a simple field method, but its efficiency has yet to be validated. We tested standard method assess recovery four common polymer microfibres and two natural fibres, under three different salinities (freshwater, brackish water, saltwater). Overall rates were low (26.8...

Abstract Microplastics are ubiquitous in our environment but their presence air is less well understood. Homes likely a key source of airborne microplastics and microfibres to the owing frequent use storage plastics textiles within them. Studying presence, concentration distribution these environments difficult without participation citizens due accessibility challenges. Few studies have examined intricacies prevalence indoor or link between exposure behavioural regulatory approaches that...

Introduction Seagrass sediments are important ‘blue carbon’ reservoirs which store climatically significant quantities of organic carbon (C org ) at the global scale. meadows that overly these also provide a range critical ecosystem services including shoreline stabilization, storm surge protection, and fisheries nursery grounds. However, controls over accumulation sources C to beds highly variable poorly understood with relative importance hydrodynamic setting, species composition canopy...

Abstract Total concentration of Ca in the foliage samples several tree species forestry was determined by HCl extraction ashed and ammonium EDTA un‐ashed samples. The results for extracts without addition La were comparable with commonly employed method when air‐acetylene flame used atomic absorption analysis.
