Water contamination by agricultural pollutants is one of the major environmental problems for terrestrial and aquatic life on earth. Recent studies have demonstrated the contamination of karst aquifers by pesticides and agricultural nutrients. However, the predominant research does not adequately address the main destination of these compounds. Also, research is targeted primarily towards Europe and North America. The objective of this study is to assess the fate of selected pesticides along the saturated layers of a karst aquifer, located in a tropical area. During a five-year period, 48 monthly collections were conducted by extracting samples from 24 shallow wells (8?9 m depth) and 24 deep wells (55?60 m depth). A total of 2880 samples were obtained. For all samples physical-chemical and pesticide analyses were performed. We found the presence of atrazine, lambdacyhalothrin, lactofen, fluazifop-p-butyl, chlorpyrifos, nitrate and nitrogen agricultural nutrients. The wells with 8?9 m depth had the highest concentration of the compounds studied in relation to deeper wells at 55?60 m. A significant difference was found regarding the types of pesticide (p<0.05) when comparing shallow and deep wells. Nutrients were also monitored and a decrease in the total nitrogen concentration between the wells with a lower depth (42.9 mg L-1) and the deepest wells (1.2 mg L-1) is observed along the period 2008?2013. |

Context. Soil structural quality (Sq) influences soil water dynamics, greenhouse gas emissions and plant productivity in natural and agricultural environments. Hence, assessing soil structural quality using simple methods is crucial to identifying potential impacts of different land uses. Aims. Identify correlations between Sq and macroinvertebrate communities in seven land use systems (LUS). Methods. Seven LUS were studied: native mixed ombrophylous forest (NF), native grassland (NG), native grass pasture (NP), Eucalyptus sp. plantation (EP, 20-years-old), no-tillage annual cropping (NT), integrated crop-livestock (ICL) and crop-livestock-forestry (ICLF). Each LUS had three plots and Sq and macrofauna community were evaluated. Sq was assessed through visual evaluation of soil structure (VESS) - a Sq score was assigned to each identified layer. Soil macrofauna were hand-sorted from each of these layers. Soil samples were taken in each LUS to describe selected chemical and physical attributes related to soil quality. Results. All LUS had non-degraded soil structure quality (Sq -< 3); however, with differences in Sq among LUS mainly in deeper layers. The VESS showed better Sq in NF (1.53) and NP (1.85) compared to the other LUS, with highest Sq scores for ICL and NG. The NP had the largest macrofauna communities (12 183 ind. m-2), comprising mainly termites and earthworms, with taxa richness highest in NF. Conclusions. Correlations between soil macrofauna (i.e. total density, termites and other groups) and Sq were observed, demonstrating that larger macrofauna populations were associated with better soil structural quality. Implications. Biological indicators, like soil macrofauna, can be easily measured at low cost and linked to visual Sq, facilitating simultaneous assessment of soil physical and biological health.
