Source of increased concentrations of phosphorus flowing into the Gulf of River Meadows (Kingisepp district of Leningrad region) was not found. Today, February 7, will visit "Phosphorite" representatives of Finnish environmental organizations and Russian regulatory authorities.
Wastewater samples, publicly taken on January 25 showed that the plant not to blame — the concentration of phosphorus in the samples taken, though higher than the established norms, but only slightly. Finnish ecologists suggest that the source may be the former development of phosphate deposits.
Recall that in November 2011, experts SYKE (Finnish Environment Institute) found a high concentration of phosphorus in the river Luga, near Kingisepp also found that in one of the streams flowing into the Meadow phosphorus concentration was 123 milligrams per liter (for comparison, in the wastewater plant "Phosphorite" holding "EuroChem" phosphorus concentration (according to the company itself) is about 3 mg per liter).
In January of this information hit the media, and then (January 25) holding "EuroChem" invited to the factory "Phosphorite" Kingisepp journalists, environmentalists and organized a public taking of water samples for phosphorus — for analysis were taken on two samples, one from the waste water Enterprise, the second — from a creek near the village of Sala Verkhovsky — in close proximity to the industrial area "Phosphorite" (the exact coordinates of sampling — the documents on the results of the study).
Thus, January 25 samples were taken on the phosphorus content specialists Central Ecoanalytical FBI lab "Center for Laboratory Analysis and Technical Measurements" (TsLATI), specialists of the plant "Phosphorite" and Finnish ecologists.
Besides, as it turned out, two days earlier, on January 23, took water samples Finnish journalist and later handed them to analyze the Finnish Environment Institute (SYKE).
Results from samples: a laboratory company (factory "Phosphorite") found: phosphorus in wastewater (Issue N 1 at p. Meadows: 2.9 mg per liter. Phosphorus in the creek village Sala — 9.3 mg per liter.) . This is almost identical to the results of research conducted by the FBI, "the Center for Laboratory Analysis and Technical Measurements in the North-West Federal District" (the test results there follow: measure the concentration of phosphorus in the river meadows of 3.1.
Concentration ratio of phosphorus in the stream of 9.2 according to the lab, "the Center for Laboratory Analysis and Technical Measurements", and Laboratory of the "Phosphorite" — 9.3).
The results of samples taken from the Finnish experts, as stated in Fontanke.fi SYKE, generally coincide with the above parameters.
In this regard, the following questions arise:
First: the concentration of phosphorus at 2.9 mg per liter — a lot or a little? It's a little more of the permitted level. In the Leningrad region for each local code of phosphorus in wastewater are set individually. For "Phosphorite" they are as follows: the concentration of phosphorus should reach 1.5 mg / l. (Fontanke.fi the data provided in the LLC of St. Petersburg NGO "Ecology and Business" (Partners HELCOM) with reference to the Neva-Ladoga Basin Water Authority-(sets standards for levels of phosphorus for the industry).
Thus, the concentration of phosphorus above the established standards. However, as commented by phone Larkovich Tatiana, Head of Public Relations "Phosphorite" First, deviations within the allowed rate, second, all the excess "Phosphorite" list in the budget for compensation and claims by the supervisory authorities to "phosphorites" no.
Secondly, of the published results of samples it is clear that the concentration of phosphorus in the stream than in the wastewater business. Hence, the source is not in the wastewater? As described Fontanke.fi, in the Finnish branch of the environmental organization HELCOM, the most likely source is located in the industrial zone "Phosphorite" waste and / or possibly undeveloped now mine (Until 2006, the "phosphorus" conducted quarrying of phosphate rock, then artificially recreate the fertility of the soil and vegetation. — Fontanka.fi).
As for the samples from Finnish journalist January 23, they showed the concentration of phosphorus in 157 milligrams per liter. In November 2011, we recall, SYKE fixed concentration of 123 milligrams per liter. How can we explain the fact that two days concentration decreased to 9.3 mg per liter? "I personally have not had the opportunity to take water samples on January 25, together with the employees of the plant" Phosphorite "I can not be absolutely sure that the samples were taken in the same stream in which we took them in November 2011 (when the maximum and have been found phosphorus — Fontanka.fi). At the moment I have no reason to blame the Laboratory of the "Phosphorite" in incorrect analysis or anything else, "- commented Fontanke.fi Seppo Kunttila (Seppo Knuuttila), senior researcher SYKE.
At the same time, the coordinates of the areas in which the samples were taken Jan. 25 from a stream close to the point where in November SYKE experts found a high concentration of phosphorus in the stream.
