Average values along the water column of pH collected in the Lake Bidighinzu

These data are seven freshwater parameters of Srebarna Lake. They are: water depth (m) of the lake, pH, conductivity, transperance Secchi (m), the amount of NO2, the amount of PO4 (mg/l) and the amount of Chlorophil a (mg/l). They were taken in May, August and November 2012 and these are data for spring, summer and winter season.

This study aimed to evaluate sediment and marine water quality in a mussel farming area of the Mar Piccolo of Taranto in five selected stations during October 2015. Marine water was collected from two different depths: surface and bottom while sediments were collected from the surface layer (0-5 cm). Marine water analysis included: temperature, salinity, dissolved oxygen, ammonia, nitrites, nitrates, silicates, orthophosphates and chlorophyll-a. Concerning sediments, different parameters were evaluated: water content, organic matter, total nitrogen and phosphorous, pH, red-ox potential and grain size classification. Moreover, different micropollutants were also evaluated in sediments: heavy metals (Hg, Cd, Pb, Cr, Cu, Ni, Zn, Al V and Fe) and Arsenic, polycyclic aromatic hydrocarbons (PAHs), polychlorobiphenyls (PCBs), organochlorinated pesticides, total hydrocarbons (C>12) and organotin compounds. Results confirmed the environmental problems of the investigated area included in a Site of National Interest and suggested the importance of the constant monitoring in this area characterized by mussel farming activities

Preila EMEP station (LT-15) on air chemistry and deposition are provided

This dataset includes results obtained from a one-year monitoring survey (from May 1984 to April 1985) of physico-chemical parameters in marine water of the Mar Piccolo of Taranto. Sampling was carried out monthly, for a total of 12 months in fifteen stations of the first inlet and ten stations of the second inlet of the Mar Piccolo of Taranto. Marine water was collected at three different depth in each sampling site: surface, middle and bottom. The selected parameters of this study were: pH, temperature, dissolved oxygen, salinity, ortho-phosphate, ammonia, nitrites and nitrates. Monthly monitoring survey in marine water represents a useful tool to evaluate seasonal changes in water parameters. Nutrients in fact represent the major sources of nutrition for phytoplankton growth in seawater (with sunlight and inorganic carbon) and increased nutrient inputs could lead to an increase in production and possible eutrophication phenomena

Data refer to on-site measurements and water samples collected in the mesotrophic eastern and eutrophic western basin of Lake Balaton. The data sets covers various physicochemical variables including water temperature, conductivity, pH, total suspended solids, Secchi depth, light extinction coefficient and chlorophyll a concentration for phytoplankton. Samples were collected with a tubular water column sampler.

The study of the physical–chemical parameters in the Mar Piccolo of Taranto, begun since the first years of the last century. In these selected studies physical–chemical characterization of marine water and sediments were carried out in the first and second inlet of the basin. In marine water, temperature, salinity, dissolved oxygen, ammonia, nitrites, nitrates, and orthophosphates were determined. In sediments physical–chemical parameters included: water content, organic matter, total nitrogen and total phosphorous, pH, red-ox potential and grain size classification. Moreover, different micropollutants were also evaluated: heavy metals (Hg, Cd, Pb, Cr, Cu, Ni, Zn, Al V and Fe) and Arsenic, polycyclic aromatic hydrocarbons (PAHs), polychlorobiphenyls (PCBs), organochlorinated pesticides and organotin compounds. These studies demonstrate the important role of water monitoring studies in the semi-enclosed basin of the Mar Piccolo with lagoon features, characterized also by mussel farming activities. Moreover, in addition to the trophic conditions of the area, data obtained from sediments characterization allow us to evaluate the possible contaminants transfer along the food chain, in order to protect human health by consumption of seafood products

Frequent chemical and physical measurements (two-week-interval all year) of saline lakes and channels - pH, salinity, O2, temperature, extend of water body, watercolor, zooplankton, bird species and numbers,...

Data for pH, SO42-, NO3-, NH4+, Cl-, K+, Na+, Ca2+, Mg2+ concentrations of bulk precipitation and throughfall, deposition of major ions and heavy metals (Pb and Cd), rainfall amount, temperature, humidity and some soil properties of the beech and spruce sample plots for 2012 year
