“…The exposure concentration for BDE-209 was determined based on previous results that the malformation rate increased slightly but insignificantly at 200 mg/L, which was, however, able to induce the biochemical responses (Zhu et al, 2014). The concentration selected for Pb was environmentally realistic (Wu et al, 2015). During the exposure, half of the exposure solutions were renewed daily.…”

“…In e-waste recycling areas, Pb is one of the most common heavy metals, and the major toxic metal present in high concentrations in environmental water samples Leung et al, 2008;Song and Li, 2015). For example, high Pb concentrations, ranging from 57 to 120 mg/L, were reported in river water near e-waste recycling areas in South China (Wu et al, 2015). The severe Pb contamination levels in the water column led to high levels of bioaccumulation in pompano (Trachinotus blochii) up to 2700 ng/g dry weight (dw) (Qiu et al, 2011).…”

“…Exchangeable K was extracted by ammonium acetate and determined by the flame photometric method. To extract the metal elements in soil, a 0.3 g soil sample was digested by a mixture of concentrated hydrochloric acid and nitric acid (3:1, v/v) using a CEM closed microwave system [30]. The concentrations of metal elements in the extract , namely, Ca, Mg, Na, Fe, Cd, Cu, Pb, Zn, As, Cr and Hg, were determined by an inductively coupled plasma mass spectrometer (ICP-MS, Thermo Fisher Corporation, Munich, Germany).…”

Direct-seeding rice has grown in popularity in recent years and is widespread in China. This study focused on the effects of pig slurry (PS) on grain quality and safety in direct-seeding rice. Application of more than 210 m 3¨h m´2 increased rice yield and dry matter accumulation, compared with conventional chemical fertilizer treatment (CK2). At the heading and maturing stage, a high dosage of PS (T6, T8 and T9 treatments) promoted uptake of Pb, Cu, Zn, Fe and Mn by rice plants and grain, but retarded uptake of Cr, Co and Ni, indicating an ability to alleviate toxicity of some heavy metals. Compared with CK2, PS alleviated the transfer of Pb, Cr, Co, Ni and Cu from straw to grain, but enhanced the transport of Zn, Fe and Mn. Although PS application slightly diminished the processing quality, including brown rice, milled rice and head milled rice, it significantly decreased the amylose content, optimized the starch profile, and improved the overall quality. The results confirmed the feasibility and safety of PS application to direct-seeding rice, and determined that PS basal and panicle fertilizer could increase yield and improve the rice quality when applied between 210 and 240 m 3¨h m´2.

“…Specific areas of interest for monitoring include advanced industrial processes, aquatic biological communities and waste-stream effluents [4]. Heavy metals can spread from waste-stream effluents in landfills, recycling areas and mine deposits, which contaminate the surrounding environment [5][6][7][8][9]. Connel et al [10] could show that there is a link between desorption of heavy metals and the pH level of the surrounding soil and water.…”

Broad-Range Hydrogel-Based pH Sensor with Capacitive Readout Manufactured on a Flexible Substrate

Environmental monitoring of land, water and air, is an area receiving greater attention because of human health and safety concerns. Monitoring the type of pollution and concentration levels is vital, so that appropriate contingency plans can be determined. To effectively monitor the environment, there is a need for new sensors and sensor systems that suits these type of measurements. However, the diversity of sensors suitable for low, battery powered-and large area sensor systems are limited. We have manufactured and characterized a flexible pH sensor using laser processing and blade coating techniques that is able to measure pH between 2.94 and 11.80. The sensor consists of an interdigital capacitance with a pH sensitive hydrogel coating. Thin sensors can reach 95% of their final value value within 3 min, and are stable after 4 min. Good repeatability was achieved in regard to cycling of the sensor with different pH and multiple measurements from dry state. We have also studied the relation between an interdigital capacitance penetration depth and hydrogels expansion. We believe that our passive sensor is suitable to be used in low power and large area sensor networks.
