The warming trends of Romania's climate create increasingly favorable conditions for the cultivation of some new and subtropical species. However, the absolute minimum temperatures in the winter period do not follow a statistically assured increasing trend in all months, and this is not similar throughout the country. The objective of this work was...
Contamination of cereals with fungi Aspergillus spp. and mycotoxins aflatoxins causes losses in the agro-food chain and cancers in animals and humans. This article assesses the occurrence of total aflatoxin contamination in common wheat in Romania during the 2015-2016 period under the influence of environmental factors and extreme weather events. W...
Mycotoxins and heavy metals are contaminants that affect harvests, animal and human health and produce economic losses. The article aims to present the occurrence of mycotoxin deoxynivalenol and heavy metals (lead, copper, arsenic, chromium, nickel, zinc, manganese, and cadmium) contamination in common wheat in Romania in the extremely dry year 201...
The study aimed to assess common wheat quality in Romania in the context of climate change to identify adaptation measures and ensure the sustainability of the agri-food system. The negative effects of extreme weather events on cereals are manifested starting from the field by affecting the quantitative and qualitative crop indicators, which leads...
Climate change affects the quantity and quality of wheat harvests with effects on food safety and security. Consequently, companies must develop and implement appropriate strategies, starting with the acquisition of grains and continuing with the reception, milling of grains and processing of intermediate products, storage and distribution-trade of...
The warming trends of Romania's climate create favourable conditions for growing sub-tropical species. Meanwhile, low temperatures during the winter period do not always follow a similar increasing tendency throughout the country. The objective of this work was to use some models that would identify areas where climate conditions are likely to be s...
This article assesses the occurrence of Fusarium-damaged kernels (FDKs) in common wheat (Triticum aestivum) under the influence of environmental factors and extreme weather events in Romania (exceptionally high air temperatures and extreme pedological drought produced by a dipole block in summer 2015, and extreme precipitation and floods produced b...
This article aims to evaluate deoxynivalenol occurrence in triticale crops in Romania in years with extreme weather events (2012: Siberian anticyclone with cold waves and heavy snowfall; 2013 and 2014: “Vb” cyclones with heavy precipitation and floods in spring). The deoxynivalenol level in triticale samples (N = 236) was quantified by ELISA. In Ro...
The reliability of short-term weather forecast provided by COSMO model in simulating reference evapotranspiration (ET0) was evaluated in 7 study sites distributed in 4 countries (Italy, Norway, Romania and Spain).

In order to identify changes in the annual temperature extremes, the Mann-Kendall non-parametric trend test has been applied to several thermal indices, recommended by the Expert Team on Climate Change Detection and Indices (ETCCDI). The indices were computed from gridded daily data of minimum and maximum temperature at 0.1° resolution (~10 km), fr...
Drought directly and indirectly affects human society in a number of ways. In many regions of the world climate change will exasperate the effects of droughts, affect national economies more intensely. The main aim of this article was to catalogue and analyze the drought impacts in the 11 Central and South Eastern European states located in the Dan...
This study aimed to assess post-harvest contamination with mycotoxins in the context of the geographic and agroclimatic conditions in Romania in 2012–2015, a period that was characterized by extreme meteorological events and the effects of climate change. The samples were randomly sampled from five agricultural regions of Romania and analyzed for m...
A comprehensive study on the chemical composition of rainwater was carried out from 2006 to 2016 in four sampling locations from the Eastern Carpathians, Romania, in order to study the differences between the precipitation chemistry and atmospheric circulations of intra-mountain and extra-mountain areas. All samples were analyzed for pH, electrical...
The global climatic changes consisting of the increased in the average air temperature and changes in the rainfall regime have led in the last decades to the extension of the agricultural areas affected by the drought phenomenon, both worldwide and in Romania. During the last half century, the drought and the phenomena associated with it, namely ar...

December 2016) in the Ciuc basin, Eastern Carpathians, Romania. The studied area is
an enclosed basin, also called 'the Carpathians cold pole'. All collected samples were
analyzed for major cations and anions. HCO3− concentrations were calculated based
on the empiri...

In the latest IPCC report (2014) it was estimated that since the mid-20th century, the number of cold days and nights has decreased and the number of warm days and nights has increased in large parts of Europe. Some recent analyses have found that mean summer maximum temperature change over Europe was +1.6 ± 0.4°C during 1880 to 2005. It seems that...
The paper is aiming to assess the climate change impacts on crop production in Timiş Plain – one of the most stable areas in terms of future climate change signals, using the CERES (Crop-Environment Resource Synthesis) model.
