“…The PCB concentrations found in this work are at ppq (parts per quadrillion) levels and are comparable with results previously obtained for the Venice Lagoon by Moret et al (2005); however they are some orders of magnitude lower than the values reported by García-Flor et al (2005) for Spanish and French coastal waters and by Zhang et al (2003b) for Chinese estuary waters.…”

Polychlorinated biphenyls (PCBs) and polycyclic aromatic hydrocarbons (PAHs) are two classes of micropollutants intensively monitored and regulated due to their toxicity, persistency and wide diffusion. Their concentrations have been investigated in sea-microlayer (SML) and sub-surface water (SSW) samples collected at two sites of the Venice Lagoon, a fragile ecosystem highly influenced by industrial and anthropogenic emissions. The total P PCB concentration varies from 0.45 ng/l to 2

“…Researches had shown that most hazardous vestigial POPs are especially difficult to be eliminated from water by activated carbon due to the lower concentration of POPs, from nanogram per liter to picogram per liter in water (Wang and Liu, 2001;Zhang et al, 2003). Consequently, it is attractive to develop novel sorbents to remove organic micropollutants from water efficiently.…”

As an effective, efficient, and economic approach for water purification, adsorbents and adsorption processes have been widely studied and applied in different aspects for a long time. In the recent years, a lot of novel adsorption processes have been developed for enhancing the efficiency of removing the organic and inorganic contaminants from water. This article reviews some new adsorbents and advanced adsorption methods that specialize in their compositions, structures, functions, and characteristics used in water treatment. The review emphasizes adsorption/catalytic oxidation process, adsorption/catalytic reduction process, adsorption coupled with redox process, biomimetic sorbent and its sorption behaviors of POPs, and modified adsorbents and their water purification efficiency.

“…Although application of OCPs such as DDTs and hexachlorocyclohexanes (HCHs) in agriculture has presumably been banned in China since 1980s, fresh inputs of DDTs and HCHs have been identified due to continued but limited usage of lindane, dicofol, and DDT-containing antifouling paints (Qiu et al 2005;Li et al 2007). Heavy usage of OCPs in the PRD have resulted in the occurrence of OCPs at high levels in water (Luo et al 2004), soil (Li et al 2006), sediment (Zhang et al 2003), and even human breast milk (Wong et al 2002). Despite a long record of OCPs in different environmental compartments in this region, few data exist on atmospheric deposition, especially dry deposition fluxes of these contaminants.…”

Organochlorine pesticides (OCPs) have variously been phased out in agricultural activities, but they are still widely detected in air, water, and soil systems due to their recalcitrant nature in the environment. The purposes of this study were to assess potential OCP pollution via dry and wet deposition over the fast developing Pearl River Delta area with 41,700 km 2 , where the main effort has been focused on emerging pollutants such as petroleum hydrocarbons and PM2.5. We quantified both the dry and wet deposition fluxes of 19 OCPs including dichlorodiphenyltrichloroethanes (DDTs), endosulfans (Endos), and hexachlorocyclohexanes (HCHs). The results showed that each year about 67.4, 42.0, 15.0, and 8.07 kg of total OCPs, DDTs, Endos, and HCHs were returned to the ground, among which 11.7, 10.4, 0.84, and 0.16 kg were in the dry deposition forms. The large spatial variations in OCP deposition fluxes indicated that OCP pollution in the air is mainly influenced on local scales because evaporation from local soil is likely the major source of the phased out OCPs. Source analysis indicated that DDTs may be still in use as antifouling agent and/or dicofol, but Endos and HCHs were mainly derived from the residual of historical usage. The study suggests that the historical OCP pollutants are persistent at high levels in this area and should not be overlooked, while we tackle emerging pollutants.
