Testing on GMOs in food and feed is routinely done using molecular techniques like DNA microarrays or qPCR.

These tests are based on screening genetic elements like p35S tNos pat or bar or event specific markers for the official GMOs like Mon810 Bt11 or GT73. The array based method combines multiplex PCR and array technology to screen samples for different potential GMO. Nutrients and pesticides must be retained in agricultural areas.

The use of pesticides and fertilization management within intensive agriculture often neglects a sustainable soil management and can lead to nutrient surpluses as well as pesticide residues that accumulate in the soil Balzer and Schulz 2015.

When preparing a study plan available data on the test substance such as its physico-chemical properties such as volatility purity reactivity such as rate of hydrolysis electrophilicity and structure-activity relationships of chemical analogues shall be taken into account. For all studies actual achieved dose in mgkg body weight as well as in other convenient units such as mgL.

The efficiency of this technique depends on a number of factors some of which are the physico-chemical properties of the soil and the ability of the introduced micro organisms to compete successfully with the indigenous soil microflora2. This includes techniques like land farming and composting. In land farming.

Physico-chemical dispersion are defined. Their relative importance depends on the nature of the rain as well as on the soils physical and chemical properties. The relations between aggregate breakdown crusting and water erosion are analysed and existing methods for the assessment of.

Biochar is charcoal that is produced by pyrolysis of biomass in the absence of oxygen.

It is used as a soil amendment. Biochar is defined by the International Biochar Initiative as The solid material obtained from the thermochemical conversion of biomass in an oxygen-limited environment. Biochar is a stable solid that is rich in carbon and can endure in soil for thousands of years.

Efficient high throughput accurate and sensitive methods for analysis of hundreds of pesticide residues are needed to provide fast turnaround time while keeping testing cost reasonably low. This symposium will bring together analytical chemists to share new developments advances and challenges in the analysis of pesticide residues in complex food samples.

Recent developments in residual. Applying PEF at relatively low temperatures will help achieve desired results including a decrease in microbial load without damaging the sensory and physico-chemical properties of products. A treatment chamber component a large electrical pulse generator system and a pump for immersing liquid food to enable persistent PEF treatment are typical PEF equipment components 44.

The utilization of biomass waste to produce valuable products has extraordinary advantages as far as both the economy and climate are concerned which have become particularly significant lately. The large-scale manufacturing of agricultural waste mainly rice by-products rice husk rice straw and rice bran empowers them to be the most broadly examined biomasses as they contain.
