Writing Style (est-writing-style)

ES&T is read across environmental chemistry, engineering, toxicology, and policy, so the writing must land the environmental significance quickly and stay legible to non-specialists — within a firm word budget. House style is ACS (numbered citations).

When to trigger

• Drafting the abstract, introduction, or conclusions
• Cutting a manuscript down to the article-type word limit
• Converting jargon-heavy prose into multidisciplinary-readable text
• Formatting citations and headings to ACS style

Structure & style ES&T expects

1. Significance up front. The abstract and the end of the introduction must answer "why does this

matter for the environment?" — concretely (system, process, magnitude), not generically.

1. Standard structure. Abstract → Introduction → Materials and Methods → Results and Discussion →

(Conclusions/Implications) → Associated Content (SI) → references; adapt for Reviews/Perspectives/ Features.

1. Write for the broad audience. Define specialist terms on first use; avoid undefined acronyms;

lead paragraphs with the point, then the evidence.

1. Word discipline. Respect the per-type cap (Research Article ~7,000; Feature ~5,000; Review

~10,000; Perspective ~4,000; Policy Analysis ~7,000 — all 待核实) and remember exhibits may count as word-equivalents. Move detail to the SI.

1. ACS style. Numbered citations in order of appearance; SI units; chemical names/formulae per

ACS conventions; an "Environmental Implications" framing where the genre fits.

1. Features are journalistic in tone; Policy Analysis speaks to the science–policy interface.

Where each section carries its weight

ES&T prose is judged section by section against a multidisciplinary reader. The recurring weakness is burying significance and over-stuffing Methods into the main text. Calibrate each section to its job:

Worked micro-example (illustrative — rewriting a flat abstract opener)

A PFAS-fate abstract, before and after (illustrative):

• Before: "Per- and polyfluoroalkyl substances were quantified in river water by LC-MS/MS at eight

sites. Concentrations of 14 analytes were determined and statistically analyzed." — all method, no significance; a non-specialist learns nothing about why it matters.

• After: "In-stream biotransformation of fluorinated precursors increased terminal perfluoroalkyl

acid load by ~40% (illustrative) over 12 km below a discharge, showing that occurrence surveys systematically under-count persistent PFAS burden and should target precursors." — system, mechanism, magnitude, and the management consequence, legible across sub-fields.

The single highest-leverage edit at ES&T: move the environmental consequence into the first two sentences of both the abstract and the end of the introduction, and push protocol detail to the SI to recover word budget.

Referee-pushback patterns and the venue-specific fix

• "Environmental significance not established." → State system + mechanism + magnitude + consequence

in the abstract and intro close; add an Environmental Implications paragraph.

• "Inaccessible to non-specialists." → Define specialist terms and acronyms on first use; lead each

paragraph with the point.

• "Over the word limit." → Move robustness and full methods to the SI; count figure word-equivalents.

Anti-patterns

• An abstract full of methods but no significance or headline result
• Generic significance ("important for the environment") with no mechanism, system, or magnitude
• Jargon and undefined acronyms that lock out non-specialist readers
• Blowing the word cap because robustness detail lives in the main text instead of the SI
• Mixed or non-ACS citation styles
• A discussion that restates results without interpreting environmental implications
