Monitoring priority substances of directives 76/464/EEC and 2000/60/EC in Greek water bodies

Abstract

The priority substances of List I, 76/464/EEC Directive, some of which belong to the new Water Framework Directive 2000/60/EC, have been monitored in the surface waters of Greece through the developed network of 53 sampling stations. The analytical methods used for the determination of these substances included Purge and Trap-Gas chromatography-Mass spectrometry for volatile and semivolatile organic compounds, Gas Chromatography-Electron Capture Detection for organochlorine insecticides, High Performance Liquid Chromatography for pentachlorophenol and Atomic Absorption Spectrometry for metals. The results have shown the presence of several priority substances in Greek surface waters, in most cases at concentrations well below the regulatory limits. However, non-compliance was observed for a limited number of compounds. The monitoring network and the analytical determinations have to be expanded to more water bodies and more priority substances, in order to safeguard the quality of Greek surface waters.

Pesticides in the surface waters of Lake Vistonis Basin, Greece: Occurrence and environmental risk assessment

“…In previous monitoring studies, Golfinopoulos et al (2003) found several organochlorine pesticides but not lindane whereas Lekkas et al (2003) were able to detect hexachlorocyclohexane, aldrin, endrin and dieldrin. Lekkas et al (2004) reported the detection of organophosphorus insecticides, triazine (including prometryn) and phenylurea (not fluometuron) herbicides.…”

Determination of volatile chlorinated hydrocarbons in water samples by static headspace gas chromatography with electron capture detection

“…Conventional methods, such as LLE , require the use of large amount of expensive high‐purity organic solvents, which are often hazardous, and is laborious, time‐consuming, and apt to form emulsions. To avoid these drawbacks, several environmentally friendly sample pretreatment techniques, including purge and trap (P&T) , direct aqueous injection (DAI) , SPME , LPME , static headspace (static HS) , headspace solid‐phase dynamic extraction (HS‐SPDE) , headspace solid‐phase microextraction (HS‐SPME) , static headspace knotted hollow fiber microextraction (HS‐K‐HPME) , headspace single drop microextraction (HS‐SDME) , and headspace liquid‐phase microextraction (HS‐LPME) , have been arisen. P&T is the pre‐concentration method for VCHCs from water most frequently used in routine analysis in the USA.…”

Μελέτη της φωτοδιάσπασης και της τοξικότητας των φυτοπροστατευτικών προϊόντων Azinphos Ethyl, Azinphos Methyl, Dimethoate, Disulfoton και Fention σε φυσικά νερά και ιζήματα

“…Η συμβολή των οργανοχλωριωμένων φυτοπροστατευτικών προϊόντων στην αύξηση της γεωρ γικής παραγωγής ήταν ιδιαίτερα καθοριστική. Αποτέλεσμα της εκτεταμένης χρήσης αυτών είναι η ανίχνευση υπολειμματικών συγκεντρώσεων τους σε επιφανειακά και υπόγεια νερά, στο έδαφος, σε στελέχη φυτών, σε ανώτερους θαλάσσιους οργανισμούς, σε πουλιά, σε ερπετά, σε θηλαστικά και τέ λος στον ίδιο τον άνθρωπο (Karadanelli et al, 1998;Golfinopoulos et al, 2003;Hernâdez et al, 2000;Ribeiro et al, 2005).…”
