This review concerns how quality in ECEC is thematized and examined in Norwegian research published in 2010–2021. The review contributes to developing relevant professional knowledge and insight into what quality in ECEC is, should be or can be. A systematic scoping review includes 97 empirical studies of quality in the Norwegian ECEC context. The results show an increase in studies addressing quality after the year 2017. Most studies use interviews and observations, i.e., qualitative data. Research based on quantitative studies mainly applies to questionnaires, whereas multi-method designs occur with the third greatest frequency. The majority of the studies are descriptive or explore relationships. A few studies concern method development, interventions or reviews of the literature. ECEC staff and ECEC teachers are the most common informants. Two-thirds of the studies included were published in English, and only one-third were published in Norwegian. Thematically, process quality emerges as the most studied dimension of quality, dominated by investigating the aspect of staff–child interactions. About one-third of the studies investigate structural quality, with most attention paid to the physical environment and the organization of the ECEC provisions. Less research is directed at result (outcome) quality and curriculum quality. This overview contributes to increased knowledge about how quality is understood and used in research, as an essential prerequisite for creating a safe and sound everyday life for children in ECEC.

Organophosphate flame retardants (OPFRs) are increasingly and widely used as substitutes for brominated flame retardants in daily life. The chemical structure of OPFRs is very similar to that of organophosphorus pesticides, leading to concerns about their neurotoxicity. A few epidemiological studies have been published with inconsistent results on this topic, and a systematic scoping review is needed to provide an overview or map of the current evidence on the relationship of OPFRs with neurodevelopmental toxicity. Therefore, MEDLINE (accessed through PubMed), Web of Science, and CNKI (Chinese National Knowledge Infrastructure) were systematically searched for articles published in the last two decades. Nine eligible articles were included in the present systematic scoping review for adherence to the predefined PECOS (population, exposure, comparison, outcome, study design) statement. Six studies were conducted in the USA, and the remaining three studies were conducted in Austria, Norway and China. A total of 2 581 children (1 203 females and 1 378 males) were included. Half of the included studies focused on the adverse effects of OPFR exposure on cognition in children, while others primarily focused on the behaviors of children. In summary, the current evidence suggests inverse associations between early-life exposure to OPFRs and the childhood intelligence quotient and internalizing behavior and positive relationships of OPFR exposure with externalizing behavior. However, some differences in the timing of sample collection for exposure measurements, in the individual OPFR metabolites available, in the neurodevelopmental scales for outcome measurement, and in the statistical methods used to analyze the data are noted. In addition, further studies are warranted to evaluate some important issues, such as sex differences in the association, exposure-sensitive periods, and cumulative exposure risk assessment. • Human studies on neurotoxicity of organophosphate flame retardants (OPFRs) were rare. • The first systematic review was conducted for OPFRs linked with child neurotoxicity. • It indicated an inverse association of OPFR with child IQ and internalizing behavior. • It suggested a positive relationship between OPFR and child externalizing behavior.
