Two main sources of nitrate emissions in groundwater were identified: * Wastewater treatment plants (WWTP) effluents that immediately sink into the karst underground. * Emissions from livestock farming and the potentially inappropriate use of manure. [...]the calculated threshold concertation for nitrate in groundwater can be applied to all these sites. The measures are as follows: * To implement the threshold value of 9.2 mgNO3-/L in groundwater as an environmental quality standard for good chemical status for the proteus habitats. * To implement appropriate measures within subvention policy to enhance good agricultural practice of manure use and penalize the pollution of environmental compartments with manure. * To introduce a strict recording of manure application on farms in the karst region. * Surveillance over the adequacy of dung pits, dung collection sites and possible leaks of slurry into the environment. * A network of stakeholders, NGOs and public bodies that might have an interest should be established and invited to identify and record all possible sources of nitrates in groundwater. * Implementation of legal terms that would prevent release of untreated or insufficiently treated wastewater to sink directly into the karst underground and groundwater.

l‐Glutamic acid, N,N‐diacetic acid, tetrasodium salt (GLDA‐Na4) (Kelforce®) is sought to be used as a zootechnical feed additive in chickens for fattening to improve the absorption of zinc from feed, reducing zinc emissions through manure and thus, affecting favourably the environment. The product has not been authorised in the European Union as a feed additive. Kelforce® is intended to be marketed as a liquid and solid formulation, containing ≥ 47% and ≥ 30% of GLDA‐Na4, respectively. Kelforce® is safe for chickens for fattening at the maximum level of 1,000 mg GLDA‐Na4/kg complete feed. Based on the toxicological profile of GLDA‐Na4 and the consumer exposure to GLDA‐Na4 and to nitrilotriacetic acid trisodium salt (NTA‐Na3; an impurity of the additive), the use of Kelforce® at the maximum proposed level in feed of chickens for fattening is of no concern for consumer safety. Due to its low inhalation toxicity, the exposure to GLDA‐Na4 is unlikely to pose a risk by inhalation. However, owing to the high‐dusting potential of the solid formulation, a risk from such high level of dust, even if toxicologically inert, cannot be excluded. Kelforce® is not a skin/eye irritant or skin sensitiser. No risks for the terrestrial compartment were identified at the maximum use level of the additive. Risks for the aquatic compartment cannot be excluded based on the secondary effect of the additive on green algae. In the absence of data, the Panel cannot conclude on the safety for the sediment compartment or the possible ground water contamination. The risk of bioaccumulation and secondary poisoning caused by the additive is considered very low. Owing to the inconsistent and conflicting results from the studies assessed, the Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) cannot conclude on the efficacy of the additive. The Panel made a recommendation regarding the levels of formaldehyde and cyanide in the active substance.

Sodium and potassium alginate are intended to be used as technological additives (functional groups: emulsifiers, stabilisers, thickeners, gelling agents and binders). Sodium alginate is intended to be used in feedingstuffs for pets, other non food‐producing animals and fish, with no maximum recommended use level. Potassium alginate is intended to be used in feedingstuffs for cats and dogs at levels up to 40,000 mg/kg feed (on dry matter). Since the functional properties of the additives are determined by the alginate content, sodium and potassium alginate were considered equivalent. The maximum dose considered safe for cats, dogs, other non food‐producing animals, salmonids and other fish is 40,000 mg alginates (sodium and potassium salts)/kg complete feed. The use of alginates in feedingstuffs for fish is of no concern for the consumer. Alginates are reported not to be irritant to the skin but mildly irritant to the eyes. They are considered as potential sensitisers to the skin and the respiratory tract. Alginates are high‐molecular‐weight polymers naturally occurring in brown algae. Their use in feedingstuffs for fish does not pose a risk for the aquatic environment. Alginates are effective as stabilisers, thickeners, gelling agent and binders. No conclusion could be drawn on the efficacy of alginates as emulsifiers.

Sodium saccharin is intended to be used as a sweetener in feed and water for drinking for piglets, pigs for fattening and veal calves. The Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) considers the proposed maximum use level of 150 mg sodium saccharin/kg feed as safe for calves and pigs for fattening. For piglets (sucking and weaned piglets), a lower level of 100 mg sodium saccharin/kg complete feed is considered safe. The corresponding maximum safe concentrations in water for drinking are 30 mg/L for piglets and 50 mg/L for pigs for fattening, respectively. The maximum safe concentrations of sodium saccharin in feed and water for drinking are derived under the premise that only one source, feed or water for drinking, contains the additive. The FEEDAP Panel concludes that no concern for the consumer would result from the use of sodium saccharin in feed and water for drinking at the dose considered safe for the target species. The precautions for handling the product proposed by the applicant are considered to be sufficient to ensure user safety. The FEEDAP Panel concludes that the use of sodium saccharin at the dose considered safe for target species is unlikely to have detrimental effects on the terrestrial and freshwater compartments. The high mobility and relative persistence of saccharin and the high persistency of its degradation product 4‐hydroxysaccharin indicate that groundwater contamination above 0.1 μg/L is likely to occur. Since the function of sodium saccharin in feed for the target species is essentially the same as that in food, the FEEDAP Panel concludes that no demonstration of efficacy is necessary.
