    Unique Identifier for Transgenic Plants

    The OECD developed the BioTrack Product Database which accommodates Unique Identifiers to each transgenic (or genetically engineered) plant that is approved for commercial use, including planting and food/feed use. These Unique Identifiers are intended to be used as "keys" to access information of each transgenic product in this database and to ensure the safety of modern biotechnology products

    Adverse Outcome Pathway on Aromatase inhibition leading to male-biased sex ratio via impacts on gonad differentiation

    This adverse outcome pathway links inhibition of aromatase activity in teleost fish during gonadogenesis to increased differentiation to testis resulting in a male-biased sex ratio in the population, and ultimately, reduced population sustainability. Most gonochoristic fish species develop either as males or females and do not change sex throughout their life span. However, in species where sexual differentiation is controlled at least to some degree by environmental factors, there can be a window of development during gonadal differentiation that is sensitive to a variety of exogenous conditions. During this window, endocrine active chemicals, aromatase inhibitors in particular, have the potential to alter gonad development and sex differentiation. This AOP is referred to as AOP 346 in the Collaborative Adverse Outcome Pathway Wiki (AOP-Wiki).

    Adverse Outcome Pathway on Androgen receptor agonism leading to male-biased sex ratio

    This adverse outcome pathway links androgen receptor agonism in teleost fish during gonadogenesis to male-biased sexual differentiation and consequently, reduced population growth rate. Sex determination in teleost fishes is highly plastic; it can be genetically or environmentally influenced. Species with environmentally-based sex determination in particular can be very sensitive to exogenous chemicals during the period of differentiation. Exogenous hormones are of ecological concern because they have the potential to alter gonad development and sex differentiation. This AOP is referred to as AOP 376 in the Collaborative Adverse Outcome Pathway Wiki (AOP-Wiki).

    Substance interaction with the pulmonary resident cell membrane components leading to pulmonary fibrosis

    Lung fibrosis is a dysregulated or exaggerated tissue repair process resulting in the thickening or scarring of lung tissue. It involves the presence of sustained or repeated exposure to a stressor and intricate dynamics between several inflammatory and immune response cells, and the microenvironment of the alveolar-capillary region consisting of both immune and non-immune cells, and the lung interstitium. This AOP is applicable to a broad group of stressors of diverse properties e.g. metal dusts, pharmacological products, fibres, microorganisms, chemicals, including novel technology-enabled stressors such as nanomaterials. This AOP is referred to as AOP 173 in the Collaborative Adverse Outcome Pathway Wiki (AOP-Wiki).

    Best Available Techniques (BAT) to Prevent and Control Industrial Pollution

    On 8 November 2023, the OECD organised a webinar to explore the current understanding of the Best Available Techniques (BAT) approaches and their future. It addressed key challenges, opportunities for the identification of promising emerging techniques for effective pollution prevention and reduction and the importance of cross-collaboration between regulatory authorities, industries, research institutes and technology providers.
