The occurrence of organic micropollutants (OMPs) in aqueous environments has potential effects on ecological safety and human health. Three kinds of OMPs (namely, pharmaceuticals, ultraviolet (UV) filters and organophosphate esters (OPEs)) in four drinking water source areas in Henan Province of China were analyzed, and their potential risks were evaluated. Among 48 target chemicals, 37 pollutants with total concentrations ranging from 403.0 to 1751.6 ng/L were detected in water, and 13 contaminants with total concentrations from 326.0 to 1465.4 ng/g (dry weight) were observed in sediment. The aqueous pollution levels in Jiangang Reservoir and Shahe Water Source Area were higher than that in Nanwan Reservoir and Baiguishan Reservoir, while the highest total amount of pollutants in sediment was found in Baiguishan Reservoir. Compared with pharmaceuticals and UV filters, OPEs presented higher concentrations in all investigated drinking water source areas. The highest observed concentration was triphenylphosphine oxide (TPPO, 865.2 ng/L) in water and tripentyl phosphate (TPeP, 1289.8 ng/g) in sediment. Moreover, the risk quotient (RQ) analysis implies that the determined aqueous contaminants exhibited high risks to algae and invertebrates, whereas moderate risk to fish was exhibited. The health risk assessment of aqueous OMPs by means of the hazard index (HI) indicates that the risks to adults and children were negligible. These observations are expected to provide useful information for the assessment of water quality in drinking water sources in Henan, China.

Willingness To Accept Compensation

Agricultural non-point source pollution (ANSP) has become one of the main sources of pollution in water source areas. An effective solution to this problem is the use of ecological compensation to encourage rural households to adopt agricultural pollution control measures. This study aims to answer two questions: How much compensation should be given to encourage rural households in water source areas to participate in ANSP control? What factors will influence their participation? In this study, paddy rice planting in water source area has been used as an example aiming to answer these questions. This study used the random parameter logit (RPL) model with survey data from 632 rural households in the Qinba water source area to empirically analyze rural households’ willingness to accept compensation for ANSP control and the influencing factors of this willingness. From this information, the compensation standards for ANSP control in a water source area were calculated. The results show that (1) compensation had a significant incentive effect on rural households’ willingness to control ANSP. The marginal compensation standard for reducing the use of fertilizer and pesticide was $3.40/ha and $2.00/ha, respectively. The compensation standard for not applying chemical fertilizer and pesticide at all was $540.23/ha. (2) There was heterogeneity in rural households’ preference for ANSP control compensation policies. Rural households characterized by younger residents, higher family income, higher perception of the ecological benefits, and higher perception of government policy were more willing to participate in the compensation policy. It is suggested that rural households showed a strong preference for ANSP control policies by considering both of their economic losses and ecological benefits. Our study contributes to the literature by enriching the evaluation method in providing references for the compensation of ANSP control policies

This research aimed to assess vegetation composition and the indicator species around water source areas of pine forest plantation. Data were collected through interview and vegetation survey. Vegetation communities were first compared using multi-response permutation procedure (MRPP) analysis. Indicator species analysis was then employed to determine the indicator species for each condition by considering historical data from the interview. Canonical correspondence analysis (CCA) and simple correlation analysis were also included. The result showed significant differences in species composition between water source areas in Watujali (lower low flow) and Silengkong (higher low flow) catchments, indicated by T = −5.104, p = 0.000. Pinus merkusii was dominant in Watujali (important value = 78%, D′ = 0.62) compared to Silengkong (important value = 41%, D' = 0.21), and in becoming an indicator species (value = 52.1, p = 0.042) for Watujali. Meanwhile, Laportea sinuata, as the specific tree of water source areas, was an indicator for Silengkong (value = 29.4, p = 0.004). At a smaller level, indicator species differentiated the two catchments, even though they shared similar in D′ and H′. Among specific plants of water source areas, only Ficus septica was an indicator for Watujali (value = 29.4, p = 0.004), given its adaptability. Specific plants of water source areas, including Laportea sinuata, Coctus spicatus, and Calocassia gigantea, were significant indicators for Silengkong catchments, illustrated by 34.6, 35.9, and 33.0 of indicator values, respectively. These results also reflected the relationship among tree vegetation change, environmental features, and the growth of smaller species, as implied by both CCA and simple correlation. This finding could be used as basic information for early assessment of environmental change and environmental restoration efforts around water source areas on pine forest plantations. Repetition of this study is suggested to be carried out in other pine forest areas, as each region sometimes has its own specific native and natural species.

Metode analisis dengan R/C ratio dan pemodelan persamaan struktural (Structural Equation Modeling). Hasil penelitian; a) sistem pertanian terintegrasi padi sawah dan ternak kerbau lebih efisien dibandingkan usahatani non integrasi (R/C integrasi 2,4795 > R/C non-integrasi), b) Kondisi internal pertanian berpengaruh positif signifikan terhadap sistem pertanian terintegrasi dengan bobot regresi standar 0.52,p<0.001, c) Kondisi internal pertanian berpengaruh langsung tidak signifikan terhadap pengembangan wilayah dengan bobot regresi standar 0.24, p < 0.001; c) Kondisi internal pertanian berpengaruh tidak langsung terhadap pengembangan wilayah melalui sistem pertanian terintegrasi padi sawah dan ternak kerbau sebesar 0.28, total pengaruh kondisi internal pertanian terhadap pengembangan wilayah sebesar 0.52. Berdasarkan hasil penelitian disarankan agar: a) pemerintah daerah melakukan pelatihan kepada petani yang mengelola pertanian sistem integrasi agar lebih baik, b) pemerintah memperhatikan kelanyakan sarana prasarana pertanian, khususnya fasilitas jalan, irigasi, c) pemerintah menyediakan bibit berkualitas, penyuluhan tentang beternak yang baik, d) pemerintah melakukan pelatihan terhadap petani dalam mengembangkan usahataninya sehingga pendapatan meningkat dan berdampak pada pengembangan wilayah, e) pemerintah membantu petani untuk mendapatkan modal usahatani yang lebih fleksibel dan harga output yang stabil.   This study aims to determine the effect of agricultural internal conditions on the integrated agricultural system between paddy field and buffalo livestock on the Humbang Hasundutan regional development. Using R / C ratio and Structural Equation Modeling, this study finds that a) the integrated agricultural system is more efficient than the non-integrated ones, with the integration R / C = 2.4795 that is higher than the non-integration one, b) Internal agricultural conditions have significant positive effects on integrated farming systems with standard regression weights of 0.52 and p <0.001, c) Internal conditions of agriculture have a direct and insignificant effect on regional development with a standard regression weight of 0.24 and p <0.001; c) Internal conditions of agriculture have an indirect effect on regional development through an integrated farming system of paddy rice and buffalo livestock of 0.28, and total effect of internal agricultural conditions on regional development of 0.52. Based on the results it is suggested that: a) the regional government should conduct training to improve the farmers agricultural integration system management, b) the government should pay attention to the maintenance of agricultural infrastructure, especially road facilities, irrigation, c) the government provides quality seeds, good information about raising livestock , d) the government should conduct trainings to support the development of farmers’ business and income increases, which at the end impacts the regional development, e) the government helps farmers to obtain more flexible farming capital and stable output prices.
