“…Beside their common occurrence in inland waters, these herbicides were selected based on their similar and low log K ow values and their availability as 14 C-labeled standards. Applied exposure concentrations were similar to those found in European inland waters, 16,22 as well as 100-fold higher (referred to as 'low', and 'high' concentrations, respectively, Table 1).…”

“…Although the EU invests huge amounts of money in the development of agriculture, 70% of it goes to provide directly to the income of farmers. Small agro-industrial enterprises go bankrupt due to the small size of payments and subsidies, the widespread use of pesticides harms not only the environment, soils [13], but also living organisms, a huge amount of nitrates gets into surface and ground waters due to abundant soil fertilization [14].…”

It is necessary to carry out state support in any case, overcoming all difficulties, because not only economic indicators, but also the well-being of the population depend on a successful food policy. In this article, we will be convinced of the need for government assistance for agricultural producers and analyze the most effective methods. Having considered the food policy of the countries of the world, we will identify the features of each of them. Let us also examine the factors that hinder the development of agriculture, endangering human and environmental safety that most countries in the world face.

“…Detected herbicide concentrations were several orders of magnitude lower than the HC5 values derived in the present review, confirming the low risk of herbicides to aquatic primary producers. Fang et al (2019) reported the minimum, median and maximum concentrations of a wide range of pesticides in Europe, China and the USA. For acetochlor, irgarol, isoproturon, MCPA, metolachlor and simazine, even the maximum concentrations were still at least a factor of 10 below the HC5 values.…”

The aim of the present review was to give an overview of the current state of science concerning herbicide exposure and toxicity to aquatic primary producers. To this end we assessed the open literature, revealing the widespread presence of (mixtures of) herbicides, inevitably leading to the exposure of non-target primary producers. Yet, herbicide concentrations show strong temporal and spatial variations. Concerning herbicide toxicity, it was concluded that the most sensitive as well as the least sensitive species differed per herbicide and that the observed effect concentrations for some herbicides were rather independent from the exposure time. More extensive ecotoxicity testing is required, especially considering macrophytes and marine herbicide toxicity. Hence, it was concluded that the largest knowledge gap concerns the effects of sediment-associated herbicides on primary producers in the marine/estuarine environment. Generally, there is no actual risk of waterborne herbicides to aquatic primary producers. Still, median concentrations of atrazine and especially of diuron measured in China, the USA and Europe represented moderate risks for primary producers. Maximum concentrations due to misuse and accidents may even cause the exceedance of almost 60% of the effect concentrations plotted in SSDs. Using bioassays to determine the effect of contaminated water and sediment and to identify the herbicides of concern is a promising addition to chemical analysis, especially for the photosynthesis-inhibiting herbicides using photosynthesis as endpoint in the bioassays. This review concluded that to come to a reliable herbicide hazard and risk assessment, an extensive catch-up must be made concerning macrophytes, the marine environment and especially sediment as overlooked and understudied environmental compartments.
