“…The surface water pollution results from rural runoff (e.g., livestock presence) and human activity. Runoff from rain and snow melt polluted with fecal matter contributes to the microbiological contamination of surface water, and a study of the Wieprz River that flows through the area of this study revealed the presence of virus particles throughout the year [52]. Additionally, particulate matter from coal combustion is deposited on surface water.…”

Renewable energy (RE) sources are often locally available and have the potential to lessen the rural dependence on the national power grid, reducing disruptions in power supplies and the heavy dependence on coal combustion. Poland faces an EU mandate of a 15% share of renewables in energy generation by 2020. However, the installations intended to supply several types of RE encountered local opposition, forcing a cancellation of the planned investments and stressing a need for understanding rural residents’ attitudes towards RE in general. Using survey data, this paper examines the perception of RE importance among rural residents in eastern Poland. The specified empirical relationship includes the sociodemographic and economic characteristics of residents. Perceptions of the links between health and specific sources of environmental pollution and actions demonstrating energy-saving behavior serve as explanatory variables. The performance of the estimated logit equation was rigorously tested. The probability of attaching importance to RE by rural residents increases most if a respondent displayed an energy-saving behavior, has certain demographic characteristics, and links health to environmental pollution caused by coal combustion. The graphic depiction of the effects of selected variables succinctly communicates possible future programs aimed at strengthening the rural population support of RE.

“…Presence of enteric viruses has been demonstrated in all sorts of waters generally used for irrigation of produce. As such, NoVs have been detected in ground water wells in the United States (Fout and others ), Korea (Cheong and others ; Park and others ), and Italy (Gabrieli and others ); in canal waters in the United States (Kayed ); in reclaimed wastewater, and in river water samples all over the world as in Poland (Kozyra and others ), in the Netherlands (Westrell and others ), in Japan (Haramoto and others ), and in South Africa (Mans and others ). Sources of irrigation water can be generally ranked by the microbial contamination hazard: in order of increasing risk these are potable or rain water, groundwater from deep wells, groundwater from shallow wells, surface water, and finally raw or inadequately treated wastewater (Pachepsky and others ).…”

Norovirus (NoV) and hepatitis A virus (HAV) are the most important foodborne viruses. Fresh produce has been identified as an important vehicle for their transmission. In order to supply a basis to identify possible prevention and control strategies, this review intends to demonstrate the fate of foodborne viruses in the farm to fork chain of fresh produce, which include the introduction routes (contamination sources), the viral survival abilities at different stages, and the reactions of foodborne viruses towards the treatments used in food processing of fresh produce. In general, the preharvest contamination comes mainly from soli fertilizer or irrigation water, while the harvest and postharvest contaminations come mainly from food handlers, which can be both symptomatic and asymptomatic. Foodborne viruses show high stabilities in all the stages of fresh produce production and processing. Low-temperature storage and other currently used preservation techniques, as well as washing by water have shown limited added value for reducing the virus load on fresh produce. Chemical sanitizers, although with limitations, are strongly recommended to be applied in the wash water in order to minimize cross-contamination. Alternatively, radiation strategies have shown promising inactivating effects on foodborne viruses. For high-pressure processing and thermal treatment, efforts have to be made on setting up treatment parameters to induce sufficient viral inactivation within a food matrix and to protect the sensory and nutritional qualities of fresh produce to the largest extent.

Buffalo River is an important water resource in the Eastern Cape Province of South Africa. Over a 1-year period (August 2010-July 2011), we assessed the prevalence of human adenoviruses (HAdVs) at a total of 6 sites on the river and three dams along its course. HAdVs were detected by real-time quantitative PCR in about 35 % of the samples with concentrations ranging from 1.2 × 10(1) genome copies (GC)/l to 4.71 × 10(3) GC/l. HAdVs were detected at 5 of the 6 sampling sites with the detection rate ranging from 8.3 % at Rooikrantz Dam to 92 % at Parkside. The HAdV concentrations across the sampling sites were as follows: Parkside (3.25 × 10(2)-4.71 × 10(3) GC/); King William's Town (1.02 × 10(2)-4.56 × 10(3) GC/l); and Eluxolzweni (1.17 × 10(2)-3.97 × 10(2) GC/l). Significantly (P < 0.05) higher concentrations were detected at the non-dam sites compared to the dam sites. A very low mean concentration of 1.86 × 10(1) HAdV GC/l was observed at Bridle Drift Dam. While HAdVs were detected only once at Rooikrantz Dam (1.74 × 10(1) GC/l), no HAdV was detected at Maden Dam. Epidemiologically important serotypes, Ad40/41, constituted 83.3 %, while Ad21 made up 16.7 % of the all HAdVs detected and were characterized by qualitative PCR. The Buffalo River presents a public health risk heightened by the presence of Ad 40/41 and Ad21. Our results make imperative the need for assessing water sources for viral contamination in the interest of public health. This work is a significant contribution to the molecular epidemiology of adenoviruses and to the best of our knowledge this is the first report on detection of enteric virus from surface waters in the Eastern Cape.
